[Means for Solving the Problems]

 In order to achieve the above object, the clogging device of the present invention is provided with a supply hopper having a discharge port at a lower end thereof, and a discharge roller is provided in the vicinity of the discharge port, and the discharge roller is provided in a circumferential direction and an axial direction of a cylindrical shaft. A scraping member, to which a number of rod-shaped members are fixed at a predetermined interval, is provided in the vicinity above the discharge roller, and the scraping member is in the opposite direction to the discharge roller and is slower than the discharge roller. It is designed to rotate at a peripheral speed.

[0008] A discharge conveyor may be provided in place of the discharge roller in consideration of the arrangement space of the soil filling device, the place where the culture soil is dropped, and the like.

Further, in order to more effectively prevent the adherence of the culture soil to the inner wall of the supply hopper and the adhesion of the culture soil in the supply hopper, the rod-shaped member whose axial direction is the diameter direction of the cylindrical shaft is used. And a bar member whose axial direction is a direction forming a predetermined angle with respect to the diametrical direction of the cylindrical shaft may be a scraping member in which they are alternately fixed to each other in the axial direction of the cylindrical shaft.

[0010]

[Action]

 The culture soil in the supply hopper flows along the inner wall of the supply hopper by the conveying force generated by the rotation of the scraping member, and is then discharged by the conveying force generated by the rotation of the discharging roller. Fall from the exit.

Since the culture soil in the supply hopper flows while being stirred by the scraping member, the soil particles do not adhere to each other in the supply hopper to form a lump, and the scraping member causes the culture soil to be closer to each other. Since the culture soil is scraped off, the culture soil does not adhere to the inner wall of the supply hopper or the discharge roller.

Since the scraping member is rotated at a peripheral speed lower than that of the discharging roller to increase the amount of the feeding of the cultivation soil by the discharging roller, the cultivation soil does not become a lump and falls bottomly. , A proper amount of culture soil always drops from the outlet.
